As a foreigner and not native English speaker, I really appreciate the loud and clear way you talk. Reading and writing is a thing but I often struggle in understanding natives while they talk. This serie is amazing and so are you, thanks for doing this :)
Thomas Pratt Translator?
Thomas Pratt good point
Thomas Pratt OP didn’t say he/she can’t write in English. English is not OP’s native language. This person is bilingual, maybe even trilingual.
Wonderful I like how he talks too
Paid random kids to post this on TH-cam. Lmao
Phil, you're an excellent host. They picked the right man.
I couldn't agree more. He is very insightful and really easy to comprehend.
And that orange shirt is simply marvelous. (really, I can't find even find the words. This episode blew my mine on how marvelously powerful the sun is, and how it can affect us too)
Astronomy has found it's shining knight.
Couldn't agree more.
He's his own star.
commandolam I'll echo Carlos Gomez here. Couldn't agree more. Thank you, CrashCourse, for picking Phil as the host for these videos. He describes abstract and overwhelming concepts in a very personable way that makes even difficult science accessible to people unfamiliar with it. Eager to see more videos featuring Phil!
He's too old.
The most intelligent prison inmate ever
Wtf dud
Wtf
Broadcasting directly from his cell.
i think he means the guys orange shirt
@@wideputin6586 Bright orange shirt
You know I just take the heat of the Sun for granted, especially growing up in Arizona. Of course the Sun is hot, I know that, you know that, we all know that. But it didn't hit me until I watched this how amazing it is that I can feel that heat from so far away. I love that little feeling of realization.
Same brooooo
Love how every subject of CC has the same intro theme, with a little pitch variations and different instruments.
The trick to landing on the Sun is to do it at night.
TrulyEvilBob Or during an eclipse
culwin naaa the moon is in the way - you need to land during winter
Zurt Or while its raining.
lol
ProfessorCrooks good idea - the rain can put out the sun!!! why doesnt NASA get on this? theyre wasting taxpayer money
Nice. The other day I was saying, I wish I had a really concise video about The Sun to show my daughter. You guys never fail!
*Hey finite I haven't seen your videos yet but I was planning to. You better have good material or else I will eat you.*
Hey Atticus! :D
It's so much more fun to talk to children about these things, rather than sit them in front of a monitor.
Their reactions are priceless.
ABitOfTheUniverse the video would be for the stuff I missed.
Finite Atticus In that case, I couldn't think of a much better complimentary source of information. Sagan's video from Cosmos here on TH-cam, regarding the sun and stars, is a little gloomy. Tyson's are more comedic, but Phil's are in that sweet spot, that Goldilocks Zone. Just the good stuff, delivered with a reasonable amount of passion for the subject matter.
I remember the day I realized the Sun was just another star when I was a child. It was a mind blowing realization and allowed me to step into a bigger world where I understood not all things I see or experienced were correct. That there are hidden meanings, connections and explanations that everywhere in the world.

ROCKET SHIP!
Humanity originally classified the sun as a PLANET. How embarrassing! Luckily we came to our senses and saw it fits the features of a STAR. And about time too!
@@TheRojo387 bruh the sun
has to be a planet because it's round, stars are pointy ⭐
Edit: spelling
"The thin corona"
*Me watching from 2020*
*corona theory 19*
Conspiracy theory: Phil (if that’s his name idk) and doctor Phil created a cult of Phil’s that created the corona virus and set the pandemic off into China..I think I just cracked the case 😳😳
@@lilywalton1418 yeah
i had to look for this
His name really is Phil Plait. See his book Death From Space.
Wow... This is why I like Crash Course, because when you are done it just leaves you going "Wow, I didn't know that." Keep up the good work guys!
10:26 looks like the Mayans made a slight miscalculation
the mayans did not miscalculate.
modern people misinterpreted the mayans.
Jokes aside, They are completely RANDOM. They cannot be predicted
Learning about the sun while sitting in warm sunlight makes it special.
Phil, thank you and everyone at CrashCourse and PBS very much for doing a phenomenal job. I love this show and the whole channel.
It needs to be said...
PRAAIIISSE THE SUN!!!!!!!
I love you good sir. PRAISE THE SUN!
no thx.
Legal Fiction Natural Fact solaire will be sad if you aren't a sunbro
praised
no way for me to bro at all, luckily.
What kind of idiot dislikes these videos? They're among the very best things one can find on TH-cam!
+Afonso de Portugal Flat earth people dislikes.
+Srdjan Smudja schmitty?
+Srdjan Smudja center of the universe people
Yeah people, like this video don't dislike. If you dislike this, the i like trains kid will say i like trains!
flat heads
CrashCourse, it's partly because of you that I started making videos (in fact, I uploaded my first videos only a couple weeks ago!) in the hopes that I can help people aspire to look at the world through a scientific perspective. And if anyone here is interested in watching more science-based videos, please give my channel a try! I strive to make my videos as visually appealing as possible, and as a grad student who is trying to put himself through school while also supporting his parents, your support and viewership would be greatly appreciated! Thank you guys :D
ScienceSid nice vids dude
I just subbed to you. Your videos are really well put together, good job bro. We need more science videos on youtube!
I normally don't check out people in the comments but for some reason you didn't come off as the typical obnoxious attetion-seeking spammer you'd normally find in the comment section. Man, am I glad that I checked you out. You just earned yourself a new subscriber! :D
How about you be a big boy and pay for advertising? You won't get active subscribers doing it like this.
***** Right. You are probably (key word is probably) a sock account of OP. There are numerous of occasions where idiots thought they could be famous by pandering on videos. Turns out they just close their channels because of how many inactive subscribers they got.
Phil, you are such an amazing host. Your passion for astronomy shows in your lectures and frankly, I am becoming more and more passionate about this subject myself because of this. Great job!
He is absolutely brilliant, and he knows how to convey important information so easily.
Excellent explanation! Thanks.
Excellent presentation..teachers should look to follow same approach in education...good job
this was one of the coolest CC episodes !
Thank you for these videos. They’re put together in a educational yet entertaining way. I’ve learned a lot.
Surprisingly this crash course makes me interested in Astronomy!
I always get a few interesting tidbits I didn't know before in every single one of this guy's episodes.
I saw the corona today at a total eclipse!!! It was amazing!
Phil, it would be great to have an episode on "practical tips on astronomy" without technology. Being the basics how to identify North and South. I'm sure there are lots of more thing one can figure out using astronomy without technology.
You guys should make a crash course on the great scientists/historical figures and their greatest works
and we all love you Crash Course make more! all your videos are awesome and learnable
First!!!! Finally. Keep on doing what youre doing Crash Course, I love you :)
Alex Blue Thanks, friend! DFTBA!
-Nicole
Alex Blue Thanks!
***** for me, you're the best thing on TH-cam right now. I really like how you explain things and I love this topic.
***** Wow, thanks!
Alex Blue PRAISE THE SUN \o/
thanks for using metric
It would be nice to cover the material density at the different depths.
Can we have a 5 year update series for Crash Course Astronomy? Like a mini-series where we go over all the things we've learned in the last 5 years?
This show has reignited my thirst for knowledge and hope, remiding me that the internet isn't all just a bright loudness distracting us from intelligence :)
I really really like this guy.Thank you crash course. RIP John green :(
I've been writing a post apocalypse story where a CME struck the Earth, causing world wide black outs. I just happened to set the CME event in 2012. Didn't even know that actually nearly happened that year until I watched this.
I really love this guy he has such a great way of speaking and explaining things.
"If solar storms were like Earth storms, a solar flare is like a tornado, and a CME is like a hurricane." -John Green
Great job Phil. Congratulations to you and your team. Thanks for making astronomy this interesting.
My favorite video so far! Thanks guys.
I love these videos… thanks Phil… you rule!
Wow, even though I already knew everything told in this video, hearing it still is truly (and not in the overused sense of the word) awesome! Great video next to the information; loved the animations.
so we are basically fucked if the sun farts on us?
Sadly, yes we are all screwed when it happens, and it's bound to eventually. Be ready!
Not in so elegant words. The sun,other stars, pulars, magnetars, supernovas, and others . I enjoy this .
The sun giveth and the sun taketh.
yep!
Excellent videos for people who want to learn about outer space, should be required viewing for flat earthers. BTW, I love the model of the NX-01 you have to the left :)
Such a concise but easily understood explanation. Crash Course Astronomy continuing to be my favorite Crash Course and probably my favorite series on TH-cam.
The Sun is also starkly white. It only look slightly yellow in our atmosphere. If you ever see an image of the Sun in space, and it isn't white, that means it's been artificially colored. It's done all the time.
There is no one true color of white light.
"The color temperature of sunlight above the atmosphere is about 5900 K."
This is so awesome! Keep doing this! You're great at it.
Wow astronomy is awesome! I really want to learn more things about the solar system and teach it to others!
CRASH COURSE you're so helpful my school uses your videos in most subjects.
This was an amazing episode. Thank you :)
Sun is love, sun is life.
filipinordabest yea
@a ramdom astronomy star wow
This series is great for passing the time while setting up a communications network in KSP.
Very informative and I enjoyed it a lot.
The 1859 event called the Carrington Event crashed the telegraph system. It was a once in a 500 year event. It will happen again in the future and the effects will be far more reaching than in 1859.
All hail the Sun! ☀️
🙆
Militant Pacifist the ☀️is a god
Yes. Chief god in pretty much all cultures across world.
_Goddess._ Her name is Amaterasu.
This might be my favorite Crash Course going right now.
We are there for you Crash course! Keep teaching the good stuff.
These Crash Course videos are going to save me from failing my science exam this semester...
CRASH COURSE PHILOSPHY PLEASE!
Oh my gosh, that would be too awesome.
This I would love to see. That and Crash Course Sociology.
This needs to happen.
they might be hesitant to touch on it since some topics might be controversial, but i would like to see it
There is Crash Course Philosophy. I believe Hank Green is the host.
All of this is so fascinating! The way you deliver the information can only be described in one word...perfection! I can’t wait to learn more from you!
Great video!! Keep it up!
"The sun is a 2 octillion ton Gorilla, we need to respect that."
Love that line😂
Please tell me I'm not the only one who rocks out to the theme song!!!!!!!!!! :D
I live in Belgium and we were supposed to see an eclipse today but it was too foggy to see anything, which sucks a lot because i don't know if i'll ever get the chance to see something like that again!
Loving this.
The only bad thing about this is that it has less than 140,000 views.
The world would be a lot better place if it had 1,400,000 views.
great video!!
i wish we had youtube when i was in school, physics would have been more interresting...
Awesome Video Series! Brillant and so great to watch!!!!!
Just imagine how different things would be if the CME occurred in 2012. And as Phil says, we'd still be recovering!
It's astonishing to think of all the things that we would have experienced if those particles from the Sun hit our planet Earth.
Earth: I’m so cool.
The Sun: Hold my Corona.
Puppy Perkins lol i was just going to say that
Ayyyyeeeee it’s corona time XD
we in Norway had a total eclipse some days ago :)
Phil,
Seeing you in person I know how passionate are you about Astronomy & Science. You are doing great job on educating us. Thank you.
These episodes are such an awesome brain workout. Cheers from a homeschooling mom in Seattle!
Harambe lives on in the Sun
Max Burger-Roy R.I. P
rip harambe the king
Where are your parents?
Considering how important and powerful the Sun is, ancient civilizations had the right idea worshiping it.
neoepochx worship its creator.
I have seen you on science channel, Phil!! you are a great astronomer and teacher!!
Love the sun animation at the beginning
Praise the Sun! And all of its terrifying yet life giving glory
So, America, are you glad you didn't allow Romney to shut down PBS?
Flashback?
Just curious.
*Fuck that guy.*
*****
During the presidential race in 2011/2012, Mitt Romney - the Republican who eventually ran against Obama - kept saying that if he became president, he would shut down PBS. That's the Public Broadcast Service, a government-funded public channel (like most democratic countries have). PBS mostly produces educational shows and other nationally-significant "boring" programs - including this particular Crash Course series - rather than producing reality TV and other stupid sh*t that makes lots of money.
The reasons why Republicans thought this was a good idea may be hard to understand if you're a rational person. Basically it's all about cutting government spending and making money.
Fortunately he didn't become president, PBS was not shut down, and we all got Crash Course Astronomy. YAY!!!
*****
What, pray tell, did I lie about? That Romney promised to shut down PBS? Because this is TH-cam, you know, the video footage is here.
I found your series during a hospital visit when being too tired for reading, Really great stuff thank you Phil.
Every episode is fantastic! Thank you Phil!
8:05 I want a banna to scale!
The sun brought us into this world and it can take us out. Respect mama Sol.
Awesome job man ive always had an affinity to your cadence and directness on how the universe works and i hope theres plenty more to come.
Hey, great work explaining such a topic! It was, to me, a perfect manner.
At the start, it seemed like this video was going cool, but it just went nuts when focusing on the Sun's magnetic field. It's great to learn about the relations between its magnetic field and the dynamics of those Solar events. Thanks a lot!
So 2012 almost happened...
In 1859 the telegraph system was brought down by the coronal mass ejection event.
coweatsman similar ejection event happened after not clapping cheeks for a year
The sun is a mass of incandescent gas, a gigantic nuclear furnace
***** The sun is a producer of videos on TH-cam such as SciShow, CrashCourse, and VlogBrothers and brother of novelist John Green.
Very informative! I'm reading a book on the sun right now and although I am learning a lot from it, I am more of a visual learner, so videos like these help me absorb the information better.
Love your show I watch them all!
I love the orange shirt :) realy nice (y)
He must be waiting to transfer to another prison lol
8:06 has this mystery been solved (since it has been 5 years and he said we may solve it soon)
Haha nice, I have a exam about the sun tomorrow, and you connected all what I have learned over the last few days in one video. Thank you for that.
This is so cool! I'm glad I stumbled apon this astronomy series!
The dislikes are from people using this for online school
4:21 Oh no the sun has Coronavirus!
Lolol
Thanks Phil! im binging these for the past couple days!
Amazing stuff, can't wait for episode 11!
This episode was so dam hot, but no mention of supernovas. Does this mean theirs going to be a whole episode on supernovas?
We're talking about the sun which won't go supernova, there still might be an episode about supernovas though.
nfetters I should have have known that lol. Yes, an episode on all the types of stars and supernovas would be cool. Don't think it could be considered CC astronomy if you didn't mention them.
Anthony Batista Hey Rob Stark.
:me hears corona :also me the suns lairs was a warning
This makes me think about the time Gabe from the USA The Office show shouted at Andy : Shut about the Sun! Great clip!
I enjoyed this learning session immensely.
